Hi Arthur 

Thanks for posting in the community. 

You can build ERDs to visualize the relationships between your databases by pulling your data directly from PostgreSQL. For more information please refer to this article from our Help Center: Entity Relationship Diagrams (ERDs).

Hope this helps please let us know if you have any other questions. 

Hi Nico

Thanks for quick response.

As I understand the only way is import/export functionality. Right?

Is there a way to link diagrams from Lucid directly to my PostgreSQL database or SQL script file. So when I will make changes on my database or script that changes make effect on the Lucid diagram automatically and vice versa.

Thanks

Arthur.

Hi Arthur 

That's correct. 

As far as I know there is no way to dynamically link your database with Lucidchart. We do have a data linking feature (only available at the Enterprise level) however but it is exclusive to Google Sheet Excel or CSV formats.

Ok.

Thanks Arthur.
